X Ad Video Title Length: The 70-Character Limit
The X ad video title length limit is 70 characters for the headline that appears under the video, according to the X Ads API reference. This is a separate field from the accompanying post text, so do not use the standard post's 280 weighted-character allowance as your video title budget.
Checked October 2026. Sources are listed at the end of the page.
Start by identifying the field you are editing. A title below a video, the text of a post and words drawn into a video are different parts of your creative. This guide covers the video title described in the X Ads API reference, not a universal text limit for every X ad format. Keep the title and accompanying post in separate draft fields so a last-minute edit does not get checked against the wrong limit.
| Field | Published specification | How to use it |
|---|---|---|
| Ad video title | Maximum 70 characters | Applies to the title or headline under the video in the X Ads API reference. |
| Standard post text | Maximum 280 weighted characters | Check the accompanying post separately. This is not the video title allowance. |
| Valid URL in post text | 23 weighted characters | Use X's URL counting rule for the post, not an assumed rule for the video title. |
| Emoji in post text | 2 weighted characters per emoji sequence | A visual character count is not the same as X's weighted post count. |
X Ad Video Title Length: The 70-Character Limit
Identify the title field before writing
Label your working document with separate spaces for the video title and post text. Use the 70-character maximum only for the title described in the X Ads API reference. If your selected format presents a different field, check that field's own specification rather than transferring this limit to it.
Draft a title that describes the actual video
Write the product or subject first, followed by the action or benefit the video demonstrates. Remove introductory phrases that add no meaning. For an illustrative product demonstration, 'See the travel bag's packing compartments' is more specific than 'Watch our exciting new product video'. These are writing examples, not performance claims.
Count and shorten the final title
Check the exact title you intend to submit against the 70-character maximum. Recount after adding a brand name or changing punctuation. Cut repeated ideas rather than deleting words that explain the offer. Do not assume that a post counter's handling of links or emoji also describes the separate title field.
Check the accompanying post with the matching tool
Use the free X Post Character Counter for the accompanying standard post. It checks weighted post length, including links and emoji. Keep this result separate from your title check: a passing post count does not establish that your video title fits. Review the title and post together for repetition and conflicting promises.
Review the asset and any AI-assisted copy
Preview the video with its proposed title and confirm that the words describe what the viewer will see. If you need alternative wording, Infinall Chat can write copy using your selected Brand Brain. Give it the title limit and the product details, then count the chosen draft yourself. Check the video file against the selected placement's requirements separately before submission.
A maximum length is not a writing target
The X Ads API specifies a maximum of 70 characters, not a requirement to fill the field. Prefer the shortest wording that still identifies the subject and makes sense without extra explanation. Keep necessary product details, but remove duplicated brand references or an opening phrase such as 'Introducing our latest'. Do not promise a result that the video cannot support. These are editorial recommendations, not additional X policy rules or a claim that shorter titles always perform better.
Do not confuse title length with X ad sizes
Searches for X ad specs and X ad dimensions often lead to requirements for different assets. A character limit controls text length; it does not tell you the required video dimensions, duration or upload format. Likewise, an image website card specification should not become your video export preset. Keep a separate checklist for the selected media placement. The related X ad image size guide is useful when preparing image cards, but it is not a substitute for video-specific requirements.
When to use Infinall AI and when not to
If your title is already written and you only need to check its length, a direct count and the destination field are the simpler approach. Infinall AI is useful when you need help drafting or rewriting copy from your saved brand context. Infinall Chat is available on Free and Pro; Auto replies are free within fair use limits, while other chat work can use credits. Neither an AI-written draft nor a passing character count should replace your review of the offer, wording and selected ad format. Infinall's platforms, files and sizes help page explains its own upload and feature rules; those are separate from X's advertising specifications.
Frequently asked questions
What is the maximum X ad video title length?
The X Ads API reference sets a maximum of 70 characters for the title or headline that appears under the video. Apply this limit to that field, not to all text associated with the ad.
Can I use the standard post limit for a video title?
No. The standard post allowance is 280 weighted characters, while the ad video title maximum is 70 characters. Count and review the fields separately.
Does the X Post Character Counter validate the video title?
Use it for the accompanying standard post. Its weighted counting rules cover post text, links and emoji. Check the title against its own limit rather than treating a valid post count as approval for the title.
